I think that that's perhaps why a thread for price checking might be desirable. Not only would it provide an ideal place for prices to be debated and ultimately decided on, but it would provide specific instances to be debated. Everyone could bring their preconceived prices for, say, a 6 carry female nyvene, and present them along with their reasoning; we'd get lots of different input from lots of different users on specific things. Over time, a fairly accurate price guide could be compiled.
